In developing nations, the road accidents are the most significant impacting action on the general public health problems. To overcome and reduce the accident on roads, many safety measures have been advanced and implemented. Still these problems were increasing. This is happening due to the safety measures were implemented by the lack of road accident data and underreporting. In this research study, With the help of surrogate safety measures which is traffic conflict technique depending upon conflict observation of several road users the conflict severity was determined for the road safety. This research study done in Thailand. For the data collection in the Bangkok city two locations were selected. That are Roundabout and Unsignalized intersection. For the analysis part in SPSS, Binary logistic model was user individually for both locations. The results from analysis shows that, road users with age {u2264} 15 years involved in a conflict travelling in the Crossing and Opposite direction were more likely to being serious conflict when compared with older age groups involved in a conflict travelling in same direction at Roundabout. While at Unsignalized intersection, Road user with age group {u2264}15 and age with 15-25 years were involved in a conflict travel in Crossing and Opposite direction during AM peak and PM peak hour more likely to be a serious conflict when compared with remain age groups travel in same direction during off peak.
